pensive device of this character whereby the material of the record tablet containingthe record grooves, that is, the outer portion, may be readily removed from the record tablet and a. fresh smooth surface presented for recording.

Another object of my invention is the provision of a shaving device bythe use of which a smooth surface for recording may be obtained on. record tablets which have large surface'irregularities, such, for ex ample, as those due to the warping of the tablet, without truing of the recording face of the tablet.

My invention alsocontemplates a device for attaining the'iforegoing objects irrespec ationis carried on. r a

A further object of my invention is to provide a manually operable device especially adapted for hom'eluse, for attaining the foregoing objects. Q l

Other objects and features of my invention will be hereinaftermore'fully described and claimed. i I

acter 1 represents aeircular pan provided with an upstanding peripheral flange 1 and preferably secured to a'wooden base or'sup-i port'2 in any suitable'manner, as by means of screws 3. The panel and base 2 comprise a support for a disk record tablet 4 to be shaved. The record 4; isremovably secured to the "support as by means of a studor rod 7o 5 extending through an openingprovided in the center of the record support, a collar" 6, preferably adjustably secured to rod '5 as by'means of a set screw 6, bearing on the;

The sleeveor bearing member 11 is adapt ed to be 'rotatably mounted on and closely fittheqportion 5. 9f therod 5. which extends;

above the collar 6, as shown in Fig. 1, and when so mounted the support 9 and the'part's carried thereby are adapted for'movement over the face of the recordtablet t about the axis of the latter and of the supportthereof consisting of the members 1 and 2. The

free'end'of the spring 17, however, now enrecord tablet 4:, the handle 19 is grasped by the hand and downward pressure is applied thereto so as to force the support 9 clownwarclly against the action of the spring 17 until the shaving edges of the knives 12 and 13 engage the face of the tablet 1, as shown in Fig. 2. At the same time, the support 9 is turned or rotated by the handle 19. about the axis of rod 5' and members 1 and 2 in a right-hand or clockwise direction. The shaving edges of the'knives 12 and 13 extend transversely of the record tablet and are preferably parallel thereto, and these knives will continue to shave, remove or scrape off the upper surface layers or portions of the tablet so long as the operator continues to rotate the support 9 about the rod 5 and to maintain-sufficient downward pressure on the handle 19 to hold the support 9 in its lowered or operative position against theaction of spring 17. The upper endof collar 6 is 'provided'with a shoulder 20 which coacts with the lower end 21 of sleeve 11 to limit the downward movement of the sleeve 21 and support 9 so as to prevent the tablet from being shaved too thin. The collar 6 may be adjusted on the rod 5, whereby the limit of downward movement of the sleeve 11 and support'9' with respect to the rod may be varied as desired'and the pressure required to force the knives to shaving position against the action of spring 17 may be regulated;

The knives 12 and 13, as shown, are less in length than the radius of the tablet 4,

1 preferably being of sucli'length as to shave thetablet only for the maximum width of the surface portion of the tablet which might be recorded upon. Therefore, the inner and outer portions 22 and23 of the tablet will always be of the full thickness of the original tablet, and theintermediate' depressed shaved portion will'be protected from injury. Furthermore, I have found that by having the outer end of the shaving' knives (or knife, where but one is used) terminate within the outer edge of the tablet, the liability of producing chatter marks or'like irregularities on the outer edge portion of the shaved surface is practically obviated. If the shaving-"knife or knives extend to or beyond the outer edge of the tablet, I find that some of these marks are invariably produced in the shaving operation.

Each of the knives 12 and 13- is preferably in the form of a thin flat blade of such resiliency as to be flexed by engagement thereof with the surface of the tablet when the support 9 is forced downwardly against the action of spring 17. Moreover, each of the flanges 11 and consequently each of the knives 12 and 13 is preferably rearwardly inclined, as clearly shown in Fig. 3. Con sequently, the shaving edges of the knives 12 and 13 are dragged-over the surface of the tablet in the rotary movement of support 9 during the shaving operation, and the surface portion ofthe tablet is shaved or scraped off.

The knives 12 and 13 will, because of their flexibility, also readily give to and follow large surface irregularities of the tablet, such as those due to warping, and at the same time will shave the surface of the tablet smooth. It is thus seen that the necessity of truing the surface of the tablet is done away with and consequently the amount of material which must be removed in order to get a smooth fresh surface suit able forrecording is greatly reduced.

An important feature of my invention re sides in the use of the two shaving knives 12 and 13, instead of one, as is customary, car- 100 ried by the support 9 in such relative posi tion that in the operation of the device, the" long transversely extending shaving edges of the knives will bear different angular relations to the radius of the tablet extending irregularities which will in any wayinter fere with the stylus in the recording operation. Even with the use of a-single flexible shaving knife such as described, asmooth recording surface will be obtained when the 12 shaving operation is carried on at certain speeds.

lVhen the shaving operation is finished, the device comprising the support 9, sleeve 11 and parts carried thereby is liftedoff the post 5, the nut 7 is unscrewed fromthe lower threaded end portion of post 5=and the blank 1 removed from the support comprising the pan 1 and base 2, and mounted on'the record support or turn table of a recording ma- 13 chine. The flange 1 of pan 1 servesto re-, tain material shaved from the tablet 4 in they pan. The record support may be provided with. a suitable handle 25, preferably-attachedto theflangel of pan 1, which serves as a means forlifting the support and also for holding the same steady during the shaving operation. g p; In the modified formof my invention shown in Fig. 4, each of the knives, 12 and 13 is secured to the support 9' at suchan angle with respect to the line. passing through the axis of sleeve 11, the screwslS;

and handle 19, that in'the rotation ofthe support 9' and parts connected therewith.
